    702 User Guide and Technical Information Quick Start Guide The 702 is an extremely powerful and fl exible portable audio recorder. Before recording, please familiarize yourself with the product. Several settings should be verifi ed or set based on individual recording needs.
  • Page 6: Routing Inputs To Tracks

    Routing Inputs to Tracks Before recording, inputs must be assigned to tracks. Each 702 input (1 and 2) can be assigned to the two recorded tracks (A and B). These 16 possible routing combinations are shown on the front panel with 4 blue LEDs.

  • Page 15: Input Setup And Control

    702 User Guide and Technical Information Input Setup and Control The 702 has two inputs and two record tracks. Inputs are selectable between analog or digital sourc- es. Analog inputs are connected with the balanced XLR connectors; digital inputs can be connected to either XLR Input 1 (AES3) or the BNC input (AES3id).
  • Page 16: Analog Inputs

    702 User Guide and Technical Information limiters will prevent unusually high input signal levels from clipping the analog input stage of the preamp.

  • Page 18: Input-To-Track Routing

    Input-to-Track Routing The 702 uses a fl exible routing scheme to assign inputs and tracks for recording. The input matrix allows any input to be routed to any recording track. Multiple inputs can be routed to a single track to create mono-mixed recordings.
  • Page 19: Selective Input Muting

    Sampling Rate and Bit Depth When recording the 702 generates uncompressed, PCM audio WAV fi les in the Broadcast Wave File format at the user-selected sampling rate and bit depth. The 702 LCD calculates available recording time based on the sampling rate, bit depth, number of tracks armed for recording and the storage media’s available capacity.
  • Page 20: Bit Depths

    Once a fi le is recorded its sampling rate and bit depth can not be changed in the recorder. The 702 does not perform sample rate conversion or bit depth changes. File conversion must be done in another en- vironment, such as an audio workstation.
  • Page 21: Word Clock

    If the 702 is slaved to external word clock, be certain that the source is stable. Loss of the word clock signal during recording can cause the 702 to revert back to its internally set sampling frequency. If this occurs, the portion of the fi...
  • Page 22: Outputs - Analog And Digital

    Outputs – Analog and Digital The 702 has two independent output buses , the Analog Output Bus (Bus 1) and the Digital Output Bus (Bus 2). Each side (left and right) of the two-channel buses are assigned audio sources indepen- dently, allowing the 702 to feed multiple audio devices with unique program content.
  • Page 23: Digital Output Bus

    40 dB. Headphone Output The 702 headphone output is a fl exible tool for monitoring audio in the fi eld. The 702 allows the user to monitor inputs, tracks, and post-record tracks in a number of combinations. MS stereo monitoring is also available in headphones.

  • Page 25: Ms Stereo Monitoring

    Headphone Warning Tones The 702 can generate an audible beep, or warning “bell”, in the headphones when an error has oc- curred. The specifi c error will be reported on the LCD. The output level of the warning bell is menu- selectable from off to –12 dBFS in the Setup Menu.

    300 mS. While giving a very good visual indication of perceived loudness, VU meters gives poor information on actual signal peaks and are virtually useless for tracking to the 702. In VU mode, the front panel meter labeling is in volume units.
  • Page 27: Output Meter

    Input Peak The 702 has a peak LED associated with each input. These LEDs illuminate when input signal reaches –3 dBFS. There is no user-adjustment to the Input Peak LEDs. These LED’s also function as indicators of input mute activity (see Input-to-Track Routing).

  • Page 32: Recording Time Calculation

    The chart above shows recording time available with the 702. Time is expressed in hours per track (track-hours) at the specifi ed data rate supported by the 702. If recording two tracks, divide the track hours fi gure by two. Similarly for four-track recording, divide track-hours by four. Note that the 702 supports additional sampling rate / bit depth combinations, however, only the most common are included below.

After recording to an external drive has stopped, it may take several seconds for the 702 to fi nish “house- keeping” on drive. This is especially true when recording to DVD-RAM disks, which generally have slower throughput than hard drives.
  • Page 44: Firewire Bus Powering

    The six-pin FireWire port on the 702 provides power for bus-powered FireWire drives. The following conditions should be observed when connecting to bus-powered drives. • Bus powering a drive requires external DC powering of the 702. The 702 cannot operate bus- powered drives from an attached Li-ion battery.
